Hi Alice,
It's true that the Halfbike requires practice and determination to master, but that's also part of the fun and the whole experience. Like any new skill one has to learn, the Halfbike can be a challenge in the beginning, but can be quite rewarding once you feel your brain adjusting to the new movements and actually getting better with time. It's all described in our learning curve graph here with some additional learning tips >
